The webinar is intended for specialists in the field of oil and gas field development and operation, who take part in conducting, interpreting, monitoring or checking well testing.

The purpose

The purpose of this webinar is to give basic knowledge of determining reservoir pressure during well testing. To define the extrapolation methods, their features, to demonstrate strengths and weaknesses. Training is conducted in the form of audiovisual delivery (presentation) and subsequent discussion and answering trainees questions.


  • quality improvement of well testing;
  • improved monitoring of field development;
  • cost saving on ineffective measurements and testing;
